In a large bowl, toss the chopped apples with lemon juice to prevent browning.
Add the chopped celery and nuts to the apples. If using, add the grape halves and gently mix.
In a small bowl, whisk together the mayonnaise (or Greek yogurt) and honey (or maple syrup) until well combined.
Fold the dressing into the apple mixture until everything is coated evenly. Season with salt and pepper to your liking.
Refrigerate the salad for at least 30 minutes to allow the flavors to meld.
If desired, serve your Creamy Apple Salad on a bed of fresh lettuce leaves for an elegant presentation.
